Declaration
public static AsyncGPUReadbackRequest Request(Texture src, int mipIndex, int x, int width, int y, int height, int z, int depth, Action<AsyncGPUReadbackRequest> callback);
Parameters
| Parameter | Description |
|---|---|
| src | Resource to read the data from. |
| size | Size in bytes of the data to be retrieved from the ComputeBuffer or GraphicsBuffer. |
| offset | Offset in bytes in the ComputeBuffer or GraphicsBuffer. |
| mipIndex | Index of the mipmap to be fetched. |
| dstFormat | Target TextureFormat of the data. If the target format is different from the format stored on the GPU, the conversion is automatic. |
| x | Starting X coordinate in pixels of the Texture data to be fetched. |
| width | Width in pixels of the Texture data to be fetched. |
| y | Starting Y coordinate in pixels of the Texture data to be fetched. |
| height | Height in pixels of the Texture data to be fetched. |
| z | Start Z coordinate in pixels for the Texture3D being fetched. Index of Start layer for TextureCube, Texture2DArray and TextureCubeArray being fetched. |
| depth | Depth in pixels for Texture3D being fetched. Number of layers for TextureCube, TextureArray and TextureCubeArray. |
| callback | An optional delegate System.Action called once the request is fullfilled. The completed request is passed as parameter to the System.Action. |
Returns
AsyncGPUReadbackRequest Returns an AsyncGPUReadbackRequest that you can use to determine when the data is available. Otherwise, a request with an error is returned.
